"Verticality, was an unfinished map from the alpha build of Insurgency. However we all saw potential in this one and decided to finish it up. With already a strong base to work from and a huge library of assets, I was able to construct this map in less than 2 months. The map went through many revisions till we were satisfied with the gameplay. Especially the center area was altered quite a bit. I created both day and night versions.
